Abstract

PURPOSE: To obtain a generator of such a signal that can assure the highest accuracy of analysis of a high-speed Fourier conversion analyzer, by providing a clock generating means, etc. which generates a clock signal which is synchronous with an external clock.
CONSTITUTION: A clock generating means generates a clock signal which is synchronous with an external clock. For instance, an external clock is supplied through a terminal 21 and then converted into a high frequency clock by a frequency converter 22. Then a frequency divider 23 divides the frequency in response to the set value of a frequency converter 22. For the output of the divider 23, the frequency is divided by a frequency divider 25 in response to the set value of a zoom coefficient setting part 26. Then the output of the divider 23 is supplied to an address counter 28 via a changeover switch 27. A waveform memory 29 reads out a waveform as the digital value in response to the set value of a selector 31, and this output is latched by a latching circuit 32 synchronously with the output of the divider 25. This latched output is converted into an analog signal by a D/A converting circuit 33.
